I keep adjacent areas separate, a small number of metres away from the 
way for the road, which essentially reflects a model of reality without 
being over pedantic about the exact distance. This includes grass in the 
middle of islands and the like. Because road widths are exaggerated in 
the renderers that means areas neatly abut them when drawn, which is 
just the way it should be IMO. If the road moves (due to inaccurate 
mapping) it does mean the area has to be moved too, which is somewhat 
inconvenient. On the other hand selecting an area which shares edges 
with ways is a pain, so there is also some loss of convenience (not to 
mention lack of reality) in sharing edges.
